Hi Alessio, You could try our Authentication Blocklist: https://docs.abusix.com/ami-production-zones/authbl This doesn't pre-emptively list cloud IPs, it only lists IPs where we've seen evidence of compromise/abuse and these come from a variety of sources, some of them I believe to be novel

We have had to do this to select users when there's evidence of a password compromise. And yes, it could be mistaken for a phish, so we don't include a password change link, direct people to our helpdesk page with instructions on finding the change password instructions, provide a local contact
